To all whom' t nmg/ concern Be it known that l, Exos PORTER, a citizeirof the United States. residing at Shelbyville. in the county of Shelby and State of;V Indiana. have .invented a new and useful Machine .for Bulling and .Polishing and Reiiioving Scratches, of which the following is a. specification. j I l lt is the. 'object of my present invention to providea machine for butting and polishing land removing scratches rapidly and etliciently at any7 desired' point. Iparticularly on glass. without producing' hair lines on the polished surface..

ln carrying` out my invention l provide a, moving` member which carries a series of rotating` meinbers alternate ones Vof which ro` tate in opposite directions,.and mount on` the faces of these 'rotating me; ie'rs some suitable hinting material. The glass or other material to bebutfed or polished or to have scratches reinot'ed from it is held in the path l'of these rotating members so that as the vmoving` member moves the .ri'itating members are brought successivelyinto''engage-4 nient with 'the glass at the 'desired place so that the bu'liing material cn'act'tlie'reon.

. The rotation of alternate rotating butling members in opposite directions effectively does the work, and prevents the 'formation of hair `line scratches on the glass'surface. Preferably7 the moving member is a wheel mounted to rotate, and the buffingymeinbcrs are 'arranged' around the periphery-fof this wheel :with their'ax'es on radii ofthe wheel. lhe'acconipanying drawing illustrates my invention. I i

` Figure 1 is a, sicleelevation of abufiing and polishing device embodying my invention: Fig. 2. is a section on the line Q-Q 4of Fig. 1; Fig. Sis an enlarged partial development of the periphery of the device shown inFig, 1. 'f f The main wheel is shown as niade of two spaced plates 9 and Vl() fastened together by screws 11 passingthrough spacing bushings 12 to hold'y the two plates at the proper distance apart. lhesetwo plates are provided with integral hollow shaft portions 13,

mounted in bearings v14 on'a suitable s up-f 'porting` frame One of the shaft portions 13 extends beyond thebeariig (to the left in Fig. "2) and has xed thereon a driving pulley 1G. vThe plate 9 is provided at its periphery with an annular flange 1T axially'projecting to.wai'd'the plate .10, with -whioh `flange a ring` 1S cooperates to provideb'earings for an annular series of shafts 19 which extend radially of the main wheel. The ring'lby is clamped to the flange 1T in any suitable manner. asby screwslZO. and both the ring and flange are radially7 grcoved to provide Athe bearings just men? tioned. The shaftsjlf) are shouldered at both ends ofthese bearings. so that thev will not inoye radially of the wheel. At their outer ends the shafts 19 are provided. with circular enlarged heads 21, the ends of which are faced with'felt '2Q or other suit- .able butling' material.- The feltpieces 'l on adjacent shafts 19 preferably are just tangent. as clear from Figs'. `1 and 3. The inner end of each shaft '19 is provided with a gear 23. which meshes-with a similar `e'eail on each of the two adjacent .shafts 19j. so that the gears t form a complete annular series. and 'so that if any shaft 19 is rotated about its axis'all the other shafts 19 are compelled to rotate also. alternate shafts rotatingin opposite directions. Sonie of the shafts 19 are provided'with radial iiiwardrextensionsl. Fig. 1 showing three of .theshafts so provided. At their inner ends the extensions 2l are provided with bevel piiiions ivhich iiiesh with a bevel gear 26 c'o-axial with the main wheel and located between. the. plates l9. and 10 and fixed on a shaft 2T which is journaled in the hollow shaft portions (ln the projecting end of the shaftfl i pulley 2S may be mounted. In opera-tion. the main wheel 9,-10 is driven byfa belt on `the drivingT pulley 1G.

The shaft- 27 may be driven by a belt on the 4pulley 2S. or iii-ay be held statioii-.iry as the.

main wheel .9-#10 rotates. as the shaft '2T and rear-2G are either held stationary or rotated at Sonie different speed from the niain wheel.'the .pinions 25 are caused to travell on the gear 21' to produce rotation of the various shafts 19 andof the circular felt por tions 22 mounted' on the outer ends of .such shafts.` As ,has already been stated. these felt portions-2'.) on alternate shafts 19 rotate in opposite directions. as indicated by the arrows in Fig". 23.

'is desired to butl'1 or polish is held 'against the faces of the felt portionsl 2; so that as the. wheel 910 rotates it isengaged successively by such felt portions, so that it is j The speed ot' rotation of fthe felt portions 22 depends upon the relagli rubbed iirst in one direction and then in thej other on account of the alternate rotation of the different feit pieces.' This produces a butling and polishing action which isv very effective and which does not produce the hair lines which are so difficult to avoid in the ordinary buifing ivliee'l.

Y v Any suitable abrasive material may be used on the felt. If aglass is scratched thescratch may be removed by holding the, scratched portion againstthe felt pieces Q2 ivhich act to wear away theglass at the sides ofsuch scratch to the desired depth to remove the scratch. All this can be done Without the necessity for the continual movement of the glass by the operator such as is required by the ordinary buliing Wheel in order to prevent hair `line scratches, so that the butiing, polishing,

and Ascratch-removing operations may be performed ivithequal etliciency by operators of less skill than that required for the ordi- @nary bufiing Wheel, lvloreover, the action 'is more yrapid thanthat of the ordinary buiiing Wlie`el,and less laborious.
